Questions in programming the chips
Posted: Fri Aug 14, 2009 4:10 am
Hi guys,
Almost there!
I'm having some issues with programming the chips. I had some errors that I discovered after first trying to program the Atmega. I finally got the chip to program successfully, but when I did, it had the "spien" option checked off and grayed out though the Screen shot n the documentation shows it as not grayed out:
is that a problem?
OK, so then I moved on to programming the pic18f2550. I wasn't sure which frequency to use...I tried them all but I kept getting a failed reading. I finally realized I had the wire to pin 3 actually going to pin 2. DOH!!
Anyway, so I fixed that, and I disconnected and reconnected the usb cable (before burning the pic-mind you) of course the windows message came up saying there was an unrecognized usb device.
So then, I programmed the pic and halfway through the programming, the device was all the sudden recognised (great!) but then winpic said the programming failed!?!
So basically, I'm not sure if I have a working device here or not and whether I should go forward with trying to install the firmware...also, I'm very unsure whether I have chosen the right frequency. Per the parts list for Dmitri's boards, I have a 20mhz and a 12 Mhz crystal...
Sorry for all the questions! It's been a big day, but I'm getting close now!
